Deadlines you save land in your own calendar. No account, no email address, nothing for us to send. Pick how far ahead you want the alerts, then subscribe.
Your calendar link will fire 2 days before, the morning of.
Works with Google, Apple and Outlook. Your client re-reads it a couple of times a day; closed listings drop off on their own.
Most people do not miss a competition because they never found it. They miss it because they found it three weeks early, meant to come back, and did not. So put the deadlines somewhere you already look: subscribe once and they arrive in your own calendar, with a day's warning and the registration link inside.

Which is exactly how
people miss them
01. Pick one list
Everything, or one type, or one city, or one platform. Subscribing to the narrowest list that still covers you is the difference between a useful calendar and one you mute.
02. Subscribe once
Your calendar app takes the link and re-reads it a couple of times a day by itself. Nothing to install, no account here, and you never have to come back to this page.
03. Get a day's warning
Every deadline arrives as an entry with an alert 24 hours before it closes, and the registration link is inside the event. Things that have closed disappear on their own.
Each list below is a calendar your app can follow. Copy link puts its address on your clipboard, and you paste that into your calendar once - from then on the deadlines arrive by themselves. It is not a file you download and it does not go stale.
Google and Apple / Outlook are shortcuts that skip the pasting. The Apple and Outlook one hands a webcal:// link to your computer, so it only works if you have a calendar app installed to receive it - if your browser says the link cannot be opened, nothing is broken, you just want Copy link instead.
One calendar, every open deadline we can find. Start here if you are not sure.

What is in an entry
The name, who is running it, the platform, the prize when one is stated, and the link to register. The entry sits at the moment registration closes, with an alert a day before, because an alert on the deadline itself only tells you what you have missed.
It cleans itself up
Closed listings stop being served, so they leave your calendar without you pruning anything. If an organiser moves a date, the entry moves with it on the next refresh rather than duplicating.
We do not know who subscribed
There is no account and no email box to fill in. Your calendar app fetches a file, the same file everyone else gets, so there is nothing here that could tell us what you saved or entered.
Everything has a ceiling
The Everything calendar carries the 400 nearest deadlines rather than all 680, because a file that size is re-downloaded by your phone twice a day. Nothing urgent is ever cut, since the list is ordered by date, and the narrower calendars are complete. Whichever one you pick says its own count in its description.
Still confirm the date
Dates move without warning and platforms are not always quick to say so. Treat the reminder as the prompt to go and look, not as the final word, and check the organiser's page before you plan a week around one.
